REGISTER.

Application filed December 7, 1920. Serial No. 428,910.

To all whom. it may concern-.-

Be it known that I, JACOB J. ALBRIGHT, a

citizen of the United States, residing at Columbus, in the county ofMuscogee and State of Georgia. have invented certain new and usefulImprovements in Registers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in actuating and reset mechanismfor counter groups, and more particularly to such as are especiallyadapted for registering the quantity of liquid being delivered to orconsumed at a given point, as, for example, the measuring of liquid fuelfor internal combustion engines.

The object in view is the effective and accurate delivery, to a countergroup, of motion from an actuator through devices susceptible of releasefor facilitating reset of the counters.

A more detail object is the facilitating of adjustment of the releasemechanism to and from the position admitting of adjustment of thecounters.

A still further object is the insurance of synchronous action of twocounter groups with respect toeach other while providing easilymanipulated means for releasing one counter group with respect to theother for enabling independent adjustment thereof.

Vith these and further objects in view as will in part hereinafterbecome apparent and in part be stated, the invention comprises certainnovel constructions, combinations and arrangements of parts assubsequently specified and claimed.

plate 4 being turned outward to form a bearing bracket 9 hereinaftermentioned.

The rear face of annulus 5 carries a vacuum chamber or housing 6 whichcqntains the ter of my co-pending application Serial No. 215,622, filedFebruary 6, 1918.

Journaled in a bracket 7 outstanding from plate 4 is a shaft 8 whichalso extends laterally through the bracket 9. Shaft 8 may be 1 05impulse-imparting mechanism not herein shown, andforming part of thesubject mat considered the power shaft since it receives impulses froman actuator hereinafter described and operated proportionately to thedelivery of fluid being measured. Counter wheels 10 10 forming a countergroup, are mounted on the shaft 8 and are connected by the usual gearingof the ordinary counter group mechanism, whereby movement of the firstwheel to the right throughout a complete revolution effects one step ofadvance of the adjacent wheel to the left, and so on throughout thecounter, group. As this counter mechanism is of the ordinary commercialtype, it is not specifically shown herein. A sleeve 11 surrounds shaft 8and extends through bracket 9 so as to form a bearing for the shaft 8,the sleeve in turn finding bearing in the bracket. The inner end ofsleeve 11, that is the end adjacent the counter group; is provided witha ter minal disc 12 formed about its periphery with serrations producingsubstantially a circular rack shapedto fit the teeth of an internal gear13 formed in the inner periphery of the counter wheel 10 at the extremeright. It is understood, of course, that each counter wheel 10 isprovided with internal gear teeth, such as seen at 13, for intermeshingwith the motion transfer mechanism from one counter wheel to the next,and the arrangement of the disc 12 on sleeve 11 with its teethinterlocking with teeth 13 is merely a convenient manner of rigidlyconnecting the sleeve 11 to the counter wheel 10, so that the counterwheel will revolve with the sleeve. Sleeve 11 at its outer end portion,has longitudinal notches 14, 14, leaving outstanding prongs or fingers15 15. A gear wheel 16 is mounted on the outer end portion of the shaft8 in position for sliding longitudinally of the shaft, the gear Wheelbeing formed with radial notches 17, 17, proportioned and arranged toaccommodate the lingers 15. so that the gear 16 is free to slidelaterally with respect to itself and longitudinally of the shaft andalong said fingers, be ing limited in such, movement in the directiontoward the counter group by the walls of the sleeve 11 at the innerterminus of the notches l4, and in its outward movement by partshereinafter described. The bore of sleeve 11 is enlarged at the outerend portion of the sleeve forming a shoulder 18, and leaving a spaceabout the shaft 8 from said shoulder to the outer end of the sleeve. Aspring 19 is coiled about the shaft 8 within the space thus formed, andhas its inner end resting against the shoulder 18 and its outer endengaging the gear wheel 16 and stressing the same outward. The outerface of gear wheel 16 is formed with clutch teeth 20 facing aco-operating clutch member 21.

having similar teeth adapted to intermesh with the teeth 20 when theclutch plate 21 and the clutch face of gear 16 are brought .intoengagement.

The clutch plate 21, at that face opposite its clutch teeth, is providedwith an outstanding boss or drum 22, about which is coiled a clutchspring 23, the spring snugly fitting the surface of the drum, and havingone end left free while the otherend is bent to form an outstandingprojectionfld. Near the outer end of the shaft 8 a' cross pin is passedthrough the shaft in.position to lie in radial notches 26, 26, formed inthe inner face of the clutch plate 21, so that when the shaft 8 isrevolved the plate 21 moves with it, the clutch spring allowing freerotation of the clutch plate in one direction but having its projectingend 24 anchored to a relatively fixed part hereinafter mentioned forpreventing movement of the clutch plate 21 when the latter is stressedangularly in the directiontending to wind the spring 23. The clutchplate 21 with its drum 22 is mounted on .the outer end portion of shaft8 in such position that when the pin 25 rests in the notches 26, theouter face of drum 22'will be substantially flush with' the outer end ofthe shaft 8.

Extending through and rotatabl y mounted in the bracket 9 is a sleeve11' structurally identical with sleeve 11 and arranged parallel thereto,and provided with a disc 12 having rack teeth interlocked with theinternal gear teeth of a counter wheel 10, being one ofa group ofcounter wheels indicated by 10, 10'. The counter wheels 10, 11) aremountedon a shaft 8. which is journaled at its inner end portion in abracket outstanding from plate 1. The shaft 8' while for convenience ofconstruction is thus journaled, may so far as its operation is concernedbe fixed to its supporting bracket. The shaft 8 extends throughout thelength of sleeve 11' and bears the same proportional relation to thesleeve as does shaft 8 with respect to s'eeve 11. The outer end portionof sleeve 11 is constructed identically the same as the outer endportion of sleeve 11. and contains a spring 19 coiled about the shaft 8and arranged to stress outwardly a gear wheel 16, the same in form asgear wheel 16. except that gear wheel 16 is not provided with clutchteeth and is not intended to be shifted along the sleeve 11. To preventany accidental shifting of gear 16. a washer 27 surrounds the shaft 8'and is provided with radial notches correspomling to the radial notchesin the gear wheel 16 for accommodating the fingers at the outer end ofsleeve 11, so that the spring 19 actually presses against the washer 27instead of against the gear wheel 16. The spring 19' functions merely totake up wear of the parts and to allow a slight flexibility of the gear16' when the gear 16 is being moved into mesh therewith undercircumstances where the cutch teeth .20 do not accurately mesh with theteeth of clutch plate 21 when being moved toward said plate. Thearrangement of spring 19' and washer 27 also enables the use of thesleeve 11 in a form in terchangeable with sleeve 11.

A frame 28 is arranged outside of the gear wheels 16, 16, and consistsof an integral plate formed between the shafts 8 and 8' with atransversely arranged sleeve 29 and at each end with an enlargement,that opposite the clutch plate 21 being in the form of an annulus 30surrounding the spring clutch 23. The material of the frame 28 isrecessed at 31 to receive the laterally extending projection 24 of thespring 23, whereby the spring is held against movement. so that, owingto the snug fit of its several helices about drum 22, the said drum willbe held against rotation in a direction tending to wind the spring 23and is left free to rotate in a direction tending to unwind the spring.To retain the frame in its given relation to the parts stated, adisc-like washer 32 overlies the enlargement 30 and covers the clutchspring 23 and clutch drum 22. The washer 32 is held in place by a screw33, which is threaded into the outer end portion of the shaft 3. Theopposite end portion of the frame 23 is formed with an enlargement 34 ofgreater proportions than the enlargement 30, taking the formsubstantially of a cross plate having its intermediate portion recessedat for accommodatingthe outer end portion of the sleeve 11' andapertured for the passage of the outer end portion of the shaft 8, theframe 28 being anchored to the shaft by a bolt 36 threaded into theshaft and having a head engaging the outer face of the frame 28. Fixedto the outstanding end portions of the cross plate forming theenlargement 31 are spring rods 37, there being preferably two such rods.one above and one below the main portion of the frame 28 and extendingsubstantially parallel thereto to points in front of the gear wheel 16.A ring 38 surrounds the clutch teeth 20 and rests normally with itsinner edge against the outer face of the gear wheel 16. and the freeends of the spring rods 37 are fixed to the ring 38 so that movement ofthe free ends of the spring rods 37 inward will stress the gear wheel 16substantially uniformly about the wheel in an axial direction along thesleeve 11. Such stress being in excess of the pressure of spring 19. thegear wheel 16 will be moved until its clutch teeth 20 freethemselves'from the teeth of clutch plate 21. and at the same time thegear teeth of wheel 16 will free themselves from the teeth of gear 16.so that both of said gear wheels may be freely revolved. and as each isstill inten locked with itsrespective sleeve the respective countergroups may be reset by revolution of the respective gear wheel whilethus freed. \Vhen the stress is re ieved from the ring 33. and it isallowed to return to its of mesh. The ,cam means may assume any of avariety of forms, and preferably consists of some form which will enablethe same physical device serving to actuate the camming parts also tocause intermesh 'of gears enabling the camming actuator to be used forresetting the gears. To this end and for the purposes of the claims, theembodiment illustrated in Figures 14, 15 and 16, and to be hereinafterdescribed in detail, is to be considered the preferred embodiment, but asimpler form of the camming mechanism is seen in Figures 2,3, 12 and 13.In this simpler form, the cam actuator has no connection with the gears.The cam actuator consists of a spindle or shaft 39 journalled in thesleeve 29, and extending through the flange or finishing plate 2, andformed outside of said-finishing plate-with a knurled head 40 forfacilitating manual manipulation. Head 10 prevents longitudinal movementof spindle 39 in one direction and a cotter pin 51'extends through thespindle 39 in position to engage one end of sleeve 29 for preventinglongitudinal movement of the spindle in the other direction. The spindle39 is itself formed into a pair of cams 41 consisting merely in eachinstance of a notch or recess formed transversely of the spindle andarranged to lie normally in line with the spring rods 37, as seen inFigure 3, so that the spring rods may extend in position for allowingthe spring 19 to retain the gear 16 with its clutch teeth 20 in meshwith the teeth of clutch plate 21. When it is desired'to resetthecounter' groups or either ofthem, it is only necessary to revolve thespindle 39 from the position shown in Figure 3 and in dotted lines inFigure 12 to the position shown in full lines in Figure 12. whereby thematerial of the spindle cams the spring rods 37 laterally and thusthrows the gear 16 to the position for allowing a .resetting operation.-Converse movement of spindle 39 will. of course, allow return of gear 16and if the gear 16 is positioned on return with its teeth 20 slightlyout of line with the spaces between the teeth of plate 21, a slightoscillation of the gear 16 will cause it to find its proper place andenable the clutch faces to close under the stress of spring 19.

As seen in Figure 1, the upper exposed this purpose, the gear wheel 16counter group may be considered the group indicating the quantity ingallons and tenth of gallons of hydro-carbon fuel in the supply tank,and the lower counter group as indicating the total number of gallonsand tenth of gallons of fuel already used. Since the lower group isactuated by the sleeve 11, its gear wheel 16 is the one which is thrownlaterally out of mesh with the clutch plate 21 whenthe spring rods 37are stressed for being left in its substantially fixed relation andbeing then free to rotate, the parts being in the relative positionindicated in full lines in Figure 12. By revolving the gear wheel 16 theupper counter group may be reset, and in actual practice, when thepresent improved mechanism is applied to an automo bile or like devicewhose functions depend upon the operation of an internal combustionengine, the upper counter group will be reset whenever a new oradditional supply of fuel is delivered to the supply tank. Ordinarily itwill not be necessary to reset the lower counter group, since it willcollectively indicate the total amount of fuel used,

but such resetting may be accomplished readily when the parts are in theposition indicated in full lines in Figure 12 by merelyrevolving thegear wheel 16. In resetting the lower group of counter wheels, thedesire ordinarily would be to return the group to zero so as to beginthe count over again, but in resetting the upper countor group thenumerical value indicated by the upper counter group is increased tocorrespond with an increase in the supply of fuel, and, duringoperation, as the fuel is supplied to the engine, the actuation of shaft8 will cause the sleeve 11 to revolve in a direction f0. increasing thenumerical showing of the lower group and the consequent actuation ofgear wheel 16 by gear wheel 16 will cause a reduction in the numericalvaluc of the upper group. Thus the actual amount of fluid fuel left inthe tank will be indicated in the upper counter group by the process ofsubtraction while the actual amount consumed will be i ndicated by thelower group by the process of addition.

By reference to Figure 4, the manner of delivery of motion through theseveral parts will become clear, it being seen that the drive shaft 8receives its power from a clutch drum 42 about which is coiled a clutchspring 43 having an outwardly turned end 44 extending into a notch in aclutch sleeve 45. The sleeve 45 surrounds the clutch spring 43 and isprovided with an actuating arm 46, the clutch spring 43 operatingidentically the same as clutch spring 23, but in a converse direction.That is to say, when the arm-46 is swung angularly the movement of thesleeve in the direction tending to open or uncoil the spring 43 will bein a direction tending to coil the spring 23 should the drum 42 andshaft 8 tend to follow the uncoiling movement of spring 43. As a matterof fact, there is no lost motion whatever in this inner clutch made upof the spring 43 and its co-operating parts, but the outer clutch madeup of the spring 23 and its cooperating parts is provided to absolutelyin sure against any possible reverse motion of shaft 8.v When the arm 46is swung angularly in the direction for tending to coil or wind thespring 43, the drum 46 is gripped instantly and moved angularlyidentically the same distance as is the'sleeve 45, the shaft 8 beingadvanced with the drum 42, and the outer clutch permitting such advancemovement since that movement is in the direction tending to open oruncoil the spring 23. The arm 46 is swung angularly by a shaft 47 towhich the, arm 46 is pivoted by a rod 48, the shaft 47 extending throughthe plates 4 and 5 to the impulse-delivering mechanism not hereindisclosed and forming art of my co-pending application above identified,which impulse mechanism is ac.- tuated proportionally to quantities offluid fuel delivered. The drum 42 may be fixed to the shaft 8 in anyappropriate manner, but is preferably merely passed onto the shaft andlocked thereto by a transverse pin 49 extending through the shaft 48 andlying in radial notches 50 formed in one face bf the drum 42, andcorresponding in construction and arrangement to "the manner of thelocking of the clutch plate 21 to the shaft 8.

When an impulse is imparted from the rod 47 through the inner clutch tothe shaft 8, the clutch plate 21 is advanced angularly the same distanceas the advance of drum 42, and shaft 8, and the said clutch plate 21imparts its motion to the gear wheel 16, which in turn imparts itsmotion to the sleeve 11, and the counter group actuated thereby. Thegear wheel 16 also imparts its motion to the gear wheel 16, but in a converse direction, so that sleev 11' is advanced angularly identically thesame distance but in a converse direction to the advance of sleeve 11,so that the counter group actuated by sleeve 11 is moved in a directionfor subtracting while the counter group actuated by sleeve 11 is movedin a direction for addition.

As a precaution against movement under momentum, such as incident to asudden thrust, the drum 42 is preferably restrained and-held to itspositive movement by an approprite drag such, for example, as seen inFigures 4 and 5, in which is shown a disc 52 fixed to the drum 42 andoutstanding therefrom beyond the sleeve 45. The periphery of disc 52 ispreferably serrated and the end of a relatively thin spring plate 53 iscaused to rest against the serrated edge under spring pressure so as toinsure against movement of the drum in either direction under suddenimpulses and not consistent with and equal to the exact angular movementof the sleeve 45. The spring 53 may be secured in place in any ofvarious ways, but. is preferably held by a screw 54 passed through aportion of the spring and threaded into the plate 4. To prevent possiblepivotal move ment of spring 53 on screw 54, the spring is extendedbeyond the screw and turned substantially at right angles to form aprojection 55 extending through an aperture 56 formed through the plates4 and, 5.

\Vith the construction of caming device for shifting the reset wheelsout of mesh and leaving them free for a resetting operation, it isnecessary to leave a portion of each ofthe gears 16, 16 exposed as, forinstance, through apertures in the finishing plate or flange 2, so as tobe accessible for manual manipulation. It is my intention, however, toprovide means enabling the complete covering of these gear wheels asseen in Figure 14, wherein the finishing plate 2 is not provided withopenings for the exposure of the reset wheels. Obviously, the finishingplate 2" may be given a contour different from that shown as may befound desirable. However, toenable the closing in of the reset wheels,gearing must be provided enablingthe resetting at least of the wheelcontrolling the upper counter group, so as to enable the resetting ofthat counter group whenever a fresh supply of fluid fuel is. provided.To this-end, the same identical mechanism is employed as abovedescribed, except as to the form of caming spindle. and the addition ofgears actuated thereby, so that the same reference numerals are employedandthe same description will apply to. the structure seen in Figures 15and 16 as that above described withthe exception of said camingapparatus and its gears which will now be set forth in detail. Journaledon the stub shaft 57 which extends rearward from one end of the crossplate-34 is an idler pinion 58 constantly in mesh with the gear wheel16. A spindle 39" iss'l idingly mounted in the sleeve 29 and is providedwith conical wedges 41, 41*, corresponding in location to the locationof the cam recesses 41 of spindle 39. The conical Wedges 41, inoperation, serve to wedge the spring rods 37 for shifting the ring 38and thus moving the gear 16 when the spindle 39 is moved longitudinallyas indicated in dotted lines in Figure 15. The spindle 39 extendsthrough the plate 2 andis formed with a knurled head 40 for facilitatingmanual manipulation. The inner end of the spindle 39 carries a gearwheel 59 which is fixed to the spindle and positioned for coming intomesh with the idler pinion 58 when the spindle 39 is moved to the dottedline position of Figure 15, so that when the cams 41 are in engagementwith spring rods 37 and are holding the spring rods in their sprungposition with the gear 16 out of mesh with gear 16. the

gear 59 will be in mesh with pinion 58. It

is then only necessary for the operator to rotate theknurled head 40 toeffect rotation of gear wheel 16' and consequent resetting of the uppercounter group.
